boiler flue gas desulfurization system design

Air Pollution Control Technology Fact Sheet

Important classifications of flue gas desulfurization (FGD) processes that have been tested on coal-fired boilers are shown in Figure 2-1. A major distinction is generally made between recovery processes, which recover S02 in useful forms such as sulfuric acid or elemental sulfur, and throwaway processes, which produce a solid or liquid waste.

Flue Gas Desulfurization Systems: Design and Operating

ABSTRACT The repOrf. describes flue gas desulfurization (FGD) systems and the design and operating parameters that are monitored to ensure proper operation. It explains how these parameters are varied to accommodate changing boiler loads and fuel char- acteristics, and describes the control of parameters to prevent such problems as scale buildup.
